Problem with inbox in squirrelmail

Hi everyone!
I'm new to unix and tied to install postfix/IMAPcourior/squirrelmail yesterday ...
I can send and receive emails but they don't show up in the INBOX in squirrelmail. However they show up in /var/spool/mail ... so how do i get them to show in squirrelmail? I did not use any tutorial i just tried my way mostly...
